Part Description

LP207795-8   CYP3A4 & CYP3A5 gene
This testing provides genotypes for CYP3A4 and CYP3A5 and determines the estimated metabolic activity. CYP3A4 and CYP3A5 cytochrome P450 enzymes are involved in the hepatic metabolism of up to 50% of all clinically used drugs. There is wide variation in enzyme activity, particularly for CYP3A4 (10-100 fold), due to both genetic and non-genetic factors. The cause of much of the variation is not yet understood. The CYP3A4 and CYP3A5 enzymes have a high degree of similarity (85% amino acid sequence homology) and they metabolism largely the same set of drugs, Though many use the CYP3A4 pathway predominantly. Genotype and metabolic activity for CYP3A4 and CYP3A5 should therefore be considered together when assessing possible effects on drug response. CYP3A4 *22 decreases enzyme activity, and is present in ~8% of Caucasians. CYP3A5 *3 is a non-functional allele, so CYPA5 *3/*3 homozygotes are non-expressors of CYP3A5. CYP3A5 *3 is the predominant CYP3A5 allele in Caucasians (prevalence of ~92%) and therefore most Caucasians have reduced or absent CYP3A5 metabolism. CYP3A5 *6 and *7 lead to decreased enzyme activity. CYP3A5 *6 and *7 are present in 11-12% of Asians and African Americans, but are essentially absent in Caucasians (frequency of 0.1%). CYP3A4 *22 is typically associated with increased response to statins (lovastatin, simvastatin, and atorvastatin), with lower doses required to gain optimal response. For CYP3A5, poor metabolizers are typically expected to require standard dosing of tacrolimus. Intermediate or extensive metabolizers are expected to require a higher starting dose of tacrolimus. Fentanyl is a key pain medication that is metabolized by CYP3A4/3A5. The CYP3A5 *3 variant has decreased clearance of this active drug. Patients with the CYP3A5 *3/*3 genotype have a higher risk of adverse events than patients with one or two *1 alleles. However, CYP3A genotype and clinical variables (delivery rate, gender, co-medications, kidney disease, BMI and serum albumin) account for less than 50% of the wide variability in serum fentanyl concentration between patients with transdermal fentanyl treatment.
